I am using the stable version of Gwyddion 2.9 on a windows XP with the
gtk-2.12.9-win32-2 runtime environment.
I have SEM images for which I want to detect the grain boundaries.
The grain boundaries have been selected in the image with the watershed
function and inverting the resulting mask.
As judged from the image, this (more or less) correctly detects the
grain boundaries.
There are two problems however:
Firstly, the statistics for the grains is incorrect, only 2 grains are
identified when using the inverted mask.
When disabling the invert of the mask, the number of grains is too high
(301), while a manual count yields 225.
Is there some setting I can adjust to get the correct grain count and
size distribution?
Secondly, when wanting to plot the distribution of the grains (with only
"Equivalent Disc Radius" selected) this results in a program crash.
Selecting only other options, e.g. "Equivalent square side" also result
in a crash.
Exporting the raw data does work however.
Is there something wrong with the GTK+ run environment I am using or is
this related to a bug in the Gwyddion version?
Best regards,
Renzo Stheins
